Abstract

Various embodiments include methods and systems to measure and calibrate an optical particle spectrometer for reporting mass concentration. In one embodiment, an optical particle spectrometer is used to measure a concentration of particulate matter in a sampled particle-laden airstream. A particle diverter, in fluid communication with the spectrometer, diverts at least a portion of the particle-laden airstream at predetermined intervals. In one example, a mass filter receives the portion of the particle-laden airstream and filters a fraction of the particles within the airstream that are above a predetermined particle size. A mass sensor measures a mass of the fraction of the particles received from the mass filter or from the particle diverter and uses a calibration communication loop to provide the measured mass to the spectrometer to apply a correction factor to report mass concentration from the optical particle spectrometer. Other methods and systems are disclosed.
